IMPROVEMENT IN GORN-OULTIVATOB.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, ALEXANDER CAMPBELL, of Oxford, in the county ofBenton, and State of Indiana, have invented a new and improvedCorn-Cultivator; and I do hereby declare that th following is a full,clear, and exact description thereof, which will enable those skilled inthe art to make and use the same, reference being bad to .theaccompanying drawings, forming part of this specification.

i This invention relates to a new and improved corn-cultivator; and itconsists in a new and improved manner of attaching the shovel-standardsto the frame of the machine, as hereinafter fully shown and described,whereby any desired pitch may be given said standards as required.

The invention also consistsin a novel manner of securing the shares tothe standards, whereby said shares may be reversed, that is to say,changed from one standard to another, and also adjusted in a straightposition so as to face the line of draught, or be placed" there or lessobliquely therewith, either to the right or left, as maybe desired. i

In the accompanying sheet of drawings- Figure 1 is a side sectional viewof my invention. v

Figures 2 and 3, horizontal sections of the same, taken through the rearstandards, as indicated by the line :c :r, fig. 1, v a

Similar letters of reference indicate corresponding part-s.-

A represents the frame of the device, which is of 'v -f'ortn, orwider atthe rear than atthe front; 13 is the draught-pole, and C the handles. I

The side pieces a a of the frame A are mortised to receive the upperends of standards D, the. mortiscs b b'eing'su fi'iciently long to admitof-the standards D working therein. I

The standards are secured in the mortises atany desired pitch or angleby means of wcdgcsor keys 0, and stay-rods d, the front ends of whichare attached to a rod, e, fitted in an eyc,f, secured to the under sideof the draught-pole, the rod e being perforated at equal distancesapart, through any of which a pin, 9, passes.

By this arrangement, any desired degree of inclination or pitch may begiven the shovels or shares E, as will be fully understood by referringto fig. 1.

The lower front parts of the standards D are chamfered oil so as to forma surf'acc at right angles with the draught-pole or line of draught, andadmit of all the shovels being reversed. any share being attached to anystandard, the former being secured to the latter, each by a bolt, a

The front shares are generally pointed, but the rear ones are nearlysquare, and theyliave oblique-shaped blocks 71; attached to their rearsides, as shown clearly in figs. 2 and 3.

.These blocks give an oblique position to the rear shares, and byreversing their position that is to say, shifting them from one rearstandard to the other, the earth may be thrown towards or from theplan'ts, as required, and in ploughing or operating in old corn-ground,the shovels'or shares, when set obliquely, work to better advantage inthrowing out the old roots or bottoms of the preceding crop.

I claim as new, and desire to sceure by Letters Patent The attaching ofthe upper ends ofthe standards B to the frame A, by pivoting the formerin mortises Z) in the latter, in connection with the rods 12 and ,theadjustable bar e attached to the draught-pole, all, arrangedsubstantially as and for the purpose set forth.
